The Trust Fund Recovery Penalty (TFRP) under IRC §6672 makes unpaid federal payroll taxes personally collectible from any individual who is “responsible” for the business and “willfully” failed to pay them. It is one of the few tools the IRS uses to pierce the corporate veil — and it applies whether the business is still operating, in bankruptcy, or long closed. Owners, officers, bookkeepers, and check-signers can all be assessed. The TFRP does not go away with the corporate entity.
What the TFRP covers
The TFRP is not a separate tax — it is a mechanism to collect the “trust fund” portion of unpaid payroll taxes personally. Trust fund taxes are the amounts withheld from employees’ paychecks: federal income tax withholding, and the employee share of Social Security and Medicare. These amounts belong to the employees; when a business withholds them and does not remit them, the IRS treats it as a violation of a trust relationship.
The TFRP equals 100% of the unpaid trust fund taxes. Interest and penalties accrue on top. The IRS may assess the TFRP against multiple individuals for the same underlying liability, then collect from whichever has assets — the assessments are joint and several.
Who qualifies as a “responsible person”
Under Treasury Regulation §301.6672-1, a responsible person is anyone with authority to direct which creditors get paid. The IRS looks at facts, not titles:
- Officers, directors, and owners
- Anyone with check-signing authority on business accounts
- Bookkeepers or CFOs with actual control over disbursement decisions
- Family members or investors who make financial decisions
- Successor management brought in to run a failing business
Being a passive shareholder, a director without operational involvement, or an employee following instructions is generally not enough. Facts matter more than titles.
What “willful” actually means
Willfulness in the TFRP context does not require malicious intent. The IRS establishes willfulness when a responsible person:
- Knew that trust fund taxes were owed and unpaid, and
- Chose to pay other creditors — rent, vendors, salaries, personal draws — while the trust fund liability went unpaid
Paying employees their gross wages while failing to remit the withheld portion is willful. Paying a supplier to keep the business operating while the payroll tax liability grows is willful. The willfulness bar is much lower than most business owners assume.
The Form 4180 interview
Before assessing the TFRP, the IRS Revenue Officer typically interviews each potentially responsible person using Form 4180, Report of Interview With Individual Relative to Trust Fund Recovery Penalty. The interview covers:
- Your title, duties, and dates of involvement with the business
- Who had check-signing authority on business accounts
- Who made decisions about which bills to pay when cash was tight
- What you knew about the payroll tax liability and when you knew it
- What actions you took (or did not take) once you knew about the liability
Statements made during a Form 4180 interview are used to build the responsibility and willfulness case. Every business owner or officer facing a Form 4180 interview should have representation. Do not treat it as informal fact-finding.
The TFRP assessment process
- The Revenue Officer identifies potentially responsible individuals and conducts Form 4180 interviews.
- The Revenue Officer prepares a proposed assessment on Form 2751 and issues Letter 1153 to each proposed responsible person.
- The proposed responsible person has 60 days from Letter 1153 to file a written protest to IRS Appeals, or 30 days to sign Form 2751 agreeing to the assessment.
- If a timely protest is filed, IRS Appeals reviews the responsibility and willfulness determination independently.
- If the assessment is sustained, the TFRP is entered on the individual’s account and becomes personally collectible — including through wage levy and lien filing.
Defenses to a TFRP assessment
The two available defenses are:
- Not a responsible person — you lacked authority to direct which creditors were paid. Effective when you were a passive shareholder, a director without operational role, or an employee with no signature authority.
- Not willful — you did not know the trust fund taxes were unpaid, or your decisions did not amount to a choice between paying the IRS and paying other creditors. Effective in cases of bookkeeper embezzlement, fraud by co-owners, or serious illness during the relevant period.
Both defenses require documented evidence: bank signature cards, board minutes, correspondence, testimony from bookkeepers. Prepare defense evidence before the Form 4180 interview, not after.
What happens if the TFRP is already assessed
Once assessed, the TFRP is personally collectible. Resolution options are the same as any other IRS collection liability:
- Installment agreement — including partial-pay installment agreement over the 10-year collection statute
- Offer in Compromise — settle for less based on Reasonable Collection Potential
- Currently Not Collectible status — pause collection when income covers only necessary living expenses
- Reconsideration — in narrow circumstances where new evidence undermines responsibility or willfulness
What to do the day you receive Letter 1153
Letter 1153 is the trigger. The 60-day protest window is the last chance to challenge the assessment before it becomes final:
- Do not sign Form 2751 acquiescing to the assessment without professional review
- Preserve every document relating to your role, signature authority, and knowledge of the payroll tax liability
- Engage an Enrolled Agent, CPA, or tax attorney experienced with TFRP defense before the 60-day protest deadline
- File a written protest to IRS Appeals if the responsibility or willfulness determination is disputable
